Excellent crystallization clearly showing the faces of the dodecahedron, even considering the typical deformation and elongation of crystals.The sample is from an old collection of Northwestern University and we’ll include the label.
Keweenaw County, Michigan USA
Specimen size: 6 × 3.6 × 3.4 cm = 2.4” × 1.4” × 1.3”

Very sharp individual Copper crystal perched on an esthetic matrix made up of other Copper crystals and partially covered by minor, but brilliant, Quartz crystals. An old classic as is proven by the label number: 334605 from the Swedish Museum of Natural
History which is included with the specimen.

A large crystal of native Copper. It is a complete floater that is very esthetic given the perfect form of the main crystal.
Osceola Mine, Osceola No. 6, Osceola, Houghton County, Michigan USA
Specimen size: 6.7 × 2.5 × 1.6 cm = 2.6” × 1.0” × 0.6”

Dendritic growths of small but very sharp crystals with very well defined faces and edges and the dominant forms of the octahedron, most of them with a very well defined spinel-twin law. Of very good quality for the locality.
Ray Mines, Scott Mountain area, Mineral Creek District, Dripping Spring Mountains, Pinal County, Arizona USA
Specimen size: 9.5 × 6 × 2.6 cm = 3.7” × 2.4” × 1.0”

Dendritic aggregates of crystals with very well defined faces and edges, on matrix. Copper is a very rare species at the classic locality of Sacarimb; specimens like this one were long believed to contain traces of gold, but precise, modern methods of analysis indicate that they consist of pure native Copper, with no other significant elements.
